Referring to FIG. 1, a rear perspective view of a vehicle 10, such as a truck, having a tailgate 12 in a down position and a first embodiment of a tie-down system is illustrated. The tailgate 12 includes an internal panel 14 that extends from an upper panel 16 to a lower panel 18. The internal panel 14 also extends between a first side panel 20 and a second side panel 22. Alternatively, the first side panel 20 and second side panel 22 may be referred to as the pair of side panels. The first side panel 20 and second side panel 22 may each be rotatably secured a cargo bed 24 by a pair of hinges 26 such that the tailgate 12 may rotate between in an up (or closed) position and a down (or opened) position. A pair of tie-down brackets 28 is secured to the exterior of the internal panel 14 between the upper panel 16 and lower panel 18. Each tie-down bracket 28 defines a C-channel 30 that extends in a direction that is substantially parallel with the first side panel 20 and second side panel 22. Substantially parallel may include any incremental value from exactly parallel to plus or minus 10° from exactly parallel. One of the tie-down brackets 28 may be secured to the internal panel 14 adjacent to the first side panel 20 while the other of the tie-down brackets 28 may be secured to the internal panel 14 adjacent to the second side panel 22.

The tie-down brackets 28 may each include a first arm 32 and a second arm 34 that extend away from each other at a center of the tie-down bracket 28. Alternatively, the first arm 32 and second arm 34 may be referred to as the pair of arms. The first arm 32 and second arm 34 of the tie-down brackets 28 may extend away from the center of the tie-down bracket 28 at a substantially perpendicular angle relative to each other. Substantially perpendicular may include any incremental value from exactly perpendicular to plus or minus 10° from exactly perpendicular. The first arm 32 of each tie-down bracket 28 may define the C-channel 30 and may be secured to the internal panel 14, while the second arm 34 of each tie-down bracket 28 may be secured to the adjacent side panel (either the first side panel 20 or second side panel 22). The first arm 32 and second arm 34 of each tie-down bracket 28 may be secured to the respective components of the tailgate 12 by a welding process or by fasteners, such as rivets, screws, bolts, or any other type of faster known to a person of ordinary skill in the art.

Referring to FIG. 2 a rear perspective view of the vehicle 10 with the tailgate 12 in an up position is illustrated. A first accessory 36 is secured to the first embodiment of the tie-down system. More specifically, the first accessory 36 is secured within the C-channels 30 of the tie-down brackets 28. The first accessory 36 includes a pair of substantially parallel bars 38 that are secured to each other by a first crossbar 40. One of the parallel bars 38 may extend into and be secured within each of the C-channels 30 of the tie-down brackets 28. A second crossbar 42 may be rotatably secured to an end of one of the parallel bars 38 and detachably connectable to an end of the other of the parallel bars 38. The second crossbar 42 may be detachably connectable to an end of one of the parallel bars 38 by latching mechanism, clipping mechanism, locking mechanism, etc. The second crossbar 42 may be configured to rotate upwards about an end of one of the parallel bars 38 when detached from the other of the parallel bars 38. When the second crossbar 42 is connected to both parallel bars 38 items (such building materials, surfboards, etc.) that are being transported within the cargo bed 24 may be secured between the first crossbar 40 and second crossbar 42 to prevent them from shifting during transport. When the tailgate 12 is in the down position, the parallel bars 38 may be adjusted within the C-channels 30 such that they extend over the floor of the cargo bed 24, which prevents the tailgate from shifting to the up position and locks the tailgate 12 in the down position.

Referring to FIGS. 3 and 4, a second accessory 44 secured to the first embodiment of the tie-down system is illustrated. More specifically, the second accessory 44 is secured within the C-channels 30 of the tie-down brackets 28. The second accessory 44 also includes a pair of substantially parallel bars 46 that are secured to each other by a crossbar 48. One of the parallel bars 46 may extend into and be secured within each of the C-channels 30 of the tie-down brackets 28. The crossbar 48 of second accessory 44 may have a circular cross-section that extends through a first orifice defined by at least one mounting bracket 50 such that the mounting bracket 50 is configured to rotate about circular cross-section of the crossbar. The mounting bracket 50 may have at least one protrusion 52 that extends outward from the first orifice that the crossbar 48 extends through. The protrusion 52 may define a second orifice that is configured to receive a fastener 54, such as bolt or pin, to rotatably secure an item of cargo (e.g., a bicycle) to the mounting bracket 50. More specifically, the mounting bracket 50 may include a pair of protrusions 52 that extend outward from the first orifice, where the pair of protrusion are divided by a slot defined within the bracket. The pair of protrusions 52 may define aligned orifices that are configured to receive the fastener 54 to rotatably secure the item of cargo to the mounting bracket 50, while the item of cargo is disposed within the slot defined between the pair of protrusions 52.

Referring to FIG. 5, the portion of the tie-down bracket 28 that defines the C-channel 30 and an accessory attachment mechanism 56 are illustrated. The C-channel 30 may consist of a first groove 58 that extends into a second groove 60 that comprises an opening to access the C-channel 30. The combination of the first groove 58 and second groove 60 may comprise a slot having a T-shaped cross-section. The accessory attachment mechanism 56 may be secured to or integral with a bar (e.g., the parallel bars 38 of the first accessory 36 or the parallel bars 46 of the second accessory 44) that is configured to slide within the first groove 58. A spring-loaded button 62 may extend from an interior cavity of the accessory attachment mechanism 56 and through an orifice such that it extends beyond an exterior surface 64 of the accessory attachment mechanism 56. When the spring-loaded button 62 is depressed, the accessory attachment mechanism 56 may freely slide back and forth within the first groove 58. When the spring-loaded button 62 is released a biasing element 66 that is disposed within the interior cavity of the accessory attachment mechanism 56 may force the spring-loaded button 62 into notches 68 defined by the tie-down bracket 28 along the second groove 60. Alternatively, an accessory device (e.g., the parallel bars 38 of the first accessory 36 or the parallel bars 46 of the second accessory 44) may be secured to the tie-down bracket 28 by a bolt/T-nut combination or T-bolt/nut combination that extends through an orifice defined by the accessory device and engages the first groove 58 of the C-channel 30.
